NiSi Filter Pro Nano AIR UV 82mm

NiSi Filter Pro Nano AIR UV 82mm – 99.9% Transmission for Crystal-Clear Protection

The NiSi Pro Nano AIR UV 82mm filter provides high-transmission optical protection tailored for photographers who demand clarity and reliability. It protects your lens from dust, scratches, and moisture while maintaining near-air transparency so your images keep their original sharpness and color fidelity.

Key benefits and use cases

Use this filter when you need reliable front-element protection without compromising image quality. Because it delivers extremely high transmission and very low reflectivity, it is suitable for landscape, travel, portrait, and commercial work where image integrity matters. Also, its construction and coatings make it suitable for demanding outdoor conditions.

Optical performance

The Air UV filter achieves a peak transmission of 99.9% using NiSi’s ULRC (Ultra Low Reflective Coating). In practical terms, this means the filter is almost as transparent as leaving the lens unfiltered. Moreover, the filter maintains an average transmission of 99.6% across the 420–680 nm range and limits reflectivity to just 0.1%, which reduces glare and unwanted reflections.

High-resolution compatibility

The NiSi Air UV filter supports cameras and lenses that exceed 100 megapixels. Therefore, it preserves fine detail and resolution for high-performance imaging systems, helping ensure that the filter does not become a bottleneck for ultra-high-resolution work.

Durability and coatings

NiSi applies a 48-layer ULRC nano-coating to the glass to improve long-term performance. This advanced coating provides scratch resistance, stain resistance, and both waterproof and oil-proof properties. As a result, the filter stands up well in harsh outdoor environments and under professional use.

UV blocking and color fidelity

The filter blocks UV light below 395 nm to reduce UV-induced interference and blue haze. This contributes to better color accuracy and clearer images, particularly in bright, high-UV conditions.

Materials and frame design

The optical element consists of rigorously selected, high-end lens-grade glass. NiSi fits that glass in an ultra-thin brass frame. The brass frame offers greater resistance to deformation compared to aluminum and features knurling for easy mounting and removal. The frame’s slim profile minimizes the risk of vignetting, even when used on ultra-wide-angle lenses.

Quality control

NiSi tests each Air UV filter using a spectrophotometer to verify transmission and reflectivity values. This strict inspection process ensures consistent optical performance across units and confirms that the filters meet NiSi’s stated specifications.
